“…Within this field, several cooperative systems have been described that are defined by the type of relationship linking the players and the conditions by which cooperation is maintained. Of these systems, the one that most resembles the mammalian-microbial symbiosis is the generous tit-for-tat cooperation system (Nowak, 2006; Perru, 2006). Within this system, two unrelated players form a collaborative alliance to exact a mutual benefit, until one player breaks the trust leading to dissolution of the cooperative system.…”

All animals live in symbiosis. Shaped by eons of co-evolution, host-bacterial associations have developed into prosperous relationships creating mechanisms for mutual benefits to both microbe and host. No better example exists in biology than the astounding numbers of bacteria harbored by the lower gastrointestinal tract of mammals. The mammalian gut represents a complex ecosystem consisting of an extraordinary number of resident commensal bacteria existing in homeostasis with the host’s immune system. Most impressive about this relationship may be the concept that the host not only tolerates, but has evolved to require colonization by beneficial microorganisms, known as commensals, for various aspects of immune development and function. The microbiota provides critical signals that promote maturation of immune cells and tissues, leading to protection from infections by pathogens. Gut bacteria also appear to contribute to non-infectious immune disorders such as inflammatory bowel disease and autoimmunity. How the microbiota influences host immune responses is an active area of research with important implications for human health. This review synthesizes emerging findings and concepts that describe the mutualism between the microbiota and mammals, specifically emphasizing the role of gut bacteria in shaping an immune response that mediates the balance between health and disease. Unlocking how beneficial bacteria affect the development of the immune system may lead to novel and natural therapies based on harnessing the immunomodulatory properties of the microbiota.

“…Therefore, counseling candidates participating in this course, after having analyze their own "self" and how this is related to the personal selves of others, participated in assignments to locate and contextualize those two-their "I" and the "I" of students and families. The goal of these activities was to foment the concept that the "I" is always in a symbiotic relationship with the "we" (Perru, 2006).…”

This article presents an interpersonal methodology designed to increase the cultural awareness of counselor candidates. This methodology was implemented through a sequence of activities, which was part of a multicultural course in the counseling credential program in a university located in Southern California. The goal was to enrich future counselor practices by promoting self-reflection processes of personal cultural beliefs. The responses of counselor candidates, gathered through two surveys, suggest that understanding their identities will ease the process of creating bridges between them and the cultural richness of students and their parents.

“…The kind of facultative symbiosis we described between C. briggsae KT0001 and Serratia sp. SCBI is probably the transient and non-specific type, 12 and this affords flexibility to the relationship. Necromenic association in nematodes, a case where one attaches and waits until its carrier host dies to use its cadaver, was suggested to be the step archetypical EPNs used towards parasitism through symbiosis with insect killing bacteria.…”

We described an association between a strain of the nematode Caenorhabditis briggsae, i.e. KT0001, and the bacteria Serratia sp. SCBI (South African Caenorhabditis briggsae isolate), which was able to kill the insect Galleria. Here we show that the Serratia sp. SCBI lines the gut of the nematode, similar to the Heterorhabditis-Photorhabdus complex, indicating that the association is possibly internal. We also expand on the relevance of this tripartite, i.e. insect-nematode-bacteria, interaction in the broader evolutionary context and Caenorhabditis natural history.
